Answer:
The birth weight associated with the lowest 1% is 4.6 pounds.
Step-by-step explanation:
Let <em>X</em> represent the birth weights of babies.
It is provided that
It is also provided that many pre-mature births weights are in the lowest 1% of births.
Let <em>x</em> represent the births weights that are in the lowest 1% of births.
That is, P (X < x) = 0.01.
⇒ P (Z < z) = 0.01
The corresponding <em>z</em>-score is, <em>z</em> = -2.33.
Compute the value of <em>x</em> as follows:
Thus, the birth weight associated with the lowest 1% is 4.6 pounds.
